And, the main path simulation laying unit 33 is also electrically connected to the wire type determination module 40, then the main path simulation laying unit 33 can transmit the main path of the distribution line corresponding to the area to be planned to the wire type determination module 40, so that the subsequent wire type determination module 40 can analyze and process the predicted power load data, and select the type of laying wire corresponding to the main path accordingly. In this way, the main path simulation laying module 30 can realize the simulation of regular and orderly cable laying in the area to be planned, divide the node power supply area according to the historical power load data corresponding to each user in the area to be planned, and facilitate the calculation of the optimal laying path of the main path corresponding to the distribution line. At the same time, the type of laying wire is selected in combination with the predicted power load data, while ensuring the normal power consumption in the area to be planned, effectively reducing the laying cost of the wire.

[0064] Specifically, the simulated connection distance acquisition subunit 331 is electrically connected to the transfer node determination unit 32, and the transfer node determination unit 32 can transmit the relevant information of the determined multiple transfer nodes (for example, the coordinate data of each transfer node, etc.) to the simulated connection distance acquisition subunit 331, and the simulated connection distance acquisition subunit 331 can simulate all the transfer nodes to be connected in sequence, and obtain the distance of the simulated connection path corresponding to the multiple simulated connections. The connection order and connection distance of the simulated connection path in different simulation processes are different. The simulated connection distance acquisition subunit 331 is also electrically connected to the simulated connection distance comparison subunit 332, and the simulated connection distance acquisition subunit 331 can transmit the distance of the simulated connection path corresponding to the multiple simulated connections to the simulated connection distance comparison subunit 332. The simulated connection distance comparison subunit 332 can compare the distances of the simulated connection paths corresponding to the multiple simulated connections, and define the simulated connection path corresponding to the minimum distance as the main path of the distribution line corresponding to the area to be planned. The simulated connection distance comparison subunit 332 is also electrically connected to the main path simulation laying subunit 333, so the simulated connection distance comparison subunit 332 can transmit the main path of the distribution line corresponding to the area to be planned to the main path simulation laying subunit 333, and the main path simulation laying subunit 333 can simulate laying along the main path according to the main path of the distribution line corresponding to the area to be planned.

That is, after obtaining the information of all transfer nodes in the area to be planned, the main path simulation laying unit 33 connects all transfer nodes, takes the shortest connection distance as the optimal path for laying the main path corresponding to the distribution line, and simulates the laying of wires along the optimal path.

[0065] Optionally, continue to refer to Figure 2 The wire type determination module 40 includes a load comparison unit 41 and a wire type determination unit 42; the load comparison unit 41 is electrically connected to the wire type determination unit 42 and the power load prediction module 20 respectively, and the load comparison unit 41 is used to compare the predicted power load data with the maximum load data of multiple types of wires to be laid; the wire type determination unit 42 is also electrically connected to the main path simulation laying module 30, and the wire type determination unit 42 is used to determine the type of wire to be laid corresponding to the second difference range as the type of laying wire corresponding to the main path.

[0066] Specifically, the wire type determination module 40 includes a load comparison unit 41 and a wire type determination unit 42. Among them, the load comparison unit 41 is electrically connected to the power load prediction module 20, and the power load prediction module 20 can transmit the predicted power load data of the area to be planned within the target safe working period to the load comparison unit 41, and the load comparison unit 41 can compare the predicted power load data with the maximum load data of multiple types of wires to be laid under the limitation of the target safe working period. The predicted power load data can also be understood as the maximum power load of the area to be planned. The load comparison unit 41 is also electrically connected to the wire type determination unit 42, and the wire type determination unit 42 can determine the type of wire to be laid corresponding to the main path based on the comparison results of the predicted power load data with the maximum load data of multiple types of wires to be laid, and the difference between the maximum load data and the predicted power load data satisfies the type of wire to be laid corresponding to the second difference range. In other words, when the maximum load-bearing data of the wire to be laid is greater than the predicted power load data, this type of wire to be laid can be used as the type of wire to be laid corresponding to the main path, that is, the wire to be laid that meets the standards is selected according to the predicted power load data as the wire to be laid for the above-mentioned optimal path.

[0067] Further, continue to refer to Figure 2 The wire type determination module 40 also includes a historical climate acquisition unit 43 and a historical climate association unit 44; the historical climate acquisition unit 43 is used to obtain the historical climate data of the area to be planned; the historical climate association unit 44 is electrically connected to the historical climate acquisition unit 43 and the load comparison unit 41 respectively, and the historical climate association unit 44 is used to determine the maximum fluctuation impact value of the historical climate data on the maximum load data of the wire to be laid according to the historical climate data of the area to be planned; the load comparison unit 41 is also used to compare the sum of the predicted power load data and the maximum fluctuation impact value with the maximum load data of multiple types of wires to be laid; the wire type determination unit 42 is also used to determine the type of wire to be laid corresponding to the second difference range as the type of wire to be laid corresponding to the main path.

[0068] First of all, it should be noted that the present embodiment additionally introduces the consideration of the impact of climate change on the power transmission capacity of the wires to be laid corresponding to the distribution lines. In this way, the impact of climate change on the power transmission capacity of the wires to be laid can be further reduced, providing practical and effective guarantee for normal electricity consumption in the area to be planned.

[0069] Specifically, the wire type determination module 40 includes a load comparison unit 41, a wire type determination unit 42, a historical climate acquisition unit 43, and a historical climate association unit 44. Among them, the historical climate acquisition unit 43 can obtain the historical climate data of the area to be planned, so as to optimize the type of wire to be laid according to the influence of the historical climate data of the area to be planned on the power transmission capacity of the wire to be laid, which can further improve the anti-climatic interference ability of the wire to be laid, and provide further guarantee for the normal power consumption of the area to be planned. The historical climate association unit 44 is electrically connected to the historical climate acquisition unit 43, and the historical climate acquisition unit 43 can transmit the acquired historical climate data of the area to be planned to the historical climate association unit 44. The historical climate association unit 44 can determine the maximum fluctuation influence value of the historical climate data on the maximum load data of the wire to be laid according to the historical climate data of the area to be planned, that is, determine the numerical value corresponding to the degree of influence of the historical climate data on the power transmission capacity of the cable. Exemplarily, the maximum fluctuation impact value can also be understood as an error value, so as to facilitate the subsequent reasonable adjustment of the predicted power load data, so that the selected wire to be laid can carry the predicted power load data and the maximum fluctuation impact value at the same time, effectively avoiding the impact of climate change on the power transmission capacity of the wire to be laid, resulting in the situation where normal power supply cannot be provided in the planned area. Exemplarily, the rated power transmission performance can be determined by collecting the specifications, materials, resistivity, permittivity and other basic parameters of the wire to be laid (exemplarily, it can be a cable), obtaining the historical climate data of the area where the cable is located, recording the actual power transmission performance of the cable under different climatic conditions, and calculating the absolute difference between the actual power transmission performance and the rated power transmission performance, which is the degree of influence of the historical climate on the cable, that is, the error value, that is, the maximum fluctuation impact value. The historical climate association unit 44 is also electrically connected to the load comparison unit 41, and the historical climate association unit 44 can transmit the determined maximum fluctuation impact value to the load comparison unit 41, and the load comparison unit 41 can also compare the sum of the predicted power load data and the maximum fluctuation impact value with the maximum load data of multiple types of wires to be laid, and the sum of the predicted power load data and the maximum fluctuation impact value can also be understood as the maximum power load of the planned area under the premise of considering climate change. And, the load comparison unit 41 is electrically connected to the wire type determination unit 42, and the wire type determination unit 42 can also predict the comparison results of the sum of the power load data and the maximum fluctuation impact value with the maximum load data of multiple types of wires to be laid, and determine the type of wire to be laid corresponding to the main path as the difference between the maximum load data and the sum of the predicted power load data and the maximum fluctuation impact value.In other words, when the maximum load-bearing data of the wire to be laid is greater than the sum of the predicted power load data and the maximum fluctuation impact value, this type of wire to be laid can be used as the type of wire to be laid corresponding to the main path, that is, the wire to be laid that meets the standards is selected according to the predicted power load data as the wire to be laid for the above-mentioned optimal path.

[0070] Optionally, Figure 3 FIG. 1 is a schematic diagram of the structure of another line planning simulation system for a power distribution system provided by an embodiment of the present invention. Figure 3 As shown, the line planning simulation system also includes an auxiliary path simulation laying module 50; the data acquisition module 10 is electrically connected to the auxiliary path simulation laying module 50, and the data acquisition module 10 is also used to obtain the future migration direction and future migration area of ​​the user cluster in the area to be planned; the auxiliary path simulation laying module 50 is used to determine the auxiliary path of the distribution line corresponding to the future migration area according to the future migration direction and future migration area of ​​the user cluster in the area to be planned, and simulate the laying along the auxiliary path; wherein the auxiliary path is connected to the main path; the wire type determination module 40 is also electrically connected to the auxiliary path simulation laying module 50, and the wire type determination module 40 is also used to determine the type of laying wire corresponding to the auxiliary path according to the preset additional power load data.

[0071] Specifically, the line planning simulation system includes a data acquisition module 10, a power load prediction module 20, a main path simulation laying module 30, a wire type determination module 40 and an auxiliary path simulation laying module 50. Among them, the data acquisition module 10 can also obtain the future migration direction and future migration area of ​​the user cluster in the area to be planned. For example, the future migration direction and future migration area of ​​the user cluster in the area to be planned can be obtained based on the record information of the relevant departments, so as to determine the specific laying of the distribution line path in the future migration area based on the future migration direction and future migration area of ​​the user cluster in the area to be planned. For example, before planning an area, it is necessary to draft a regional planning document. The regional planning document is a strategy document, and the specific analysis and determination of the future migration direction and future migration area of ​​the user cluster can be fully realized from the regional planning document. The auxiliary path simulation laying module 50 is electrically connected to the data acquisition module 10, and the data acquisition module 10 can transmit the future migration direction and future migration area of ​​the user cluster in the area to be planned to the auxiliary path simulation laying module 50. The auxiliary path simulation laying module 50 can determine the auxiliary path of the distribution line corresponding to the future migration area according to the future migration direction and future migration area of ​​the user cluster in the area to be planned, and simulate laying along the auxiliary path, wherein the auxiliary path is connected to the main path. It can be understood that the auxiliary path can be used to distribute electricity to each user in the future migration area, and ensure the normal power consumption of each user in the area to be planned and the future migration area. Exemplarily, the entire future migration area can be understood as a node power supply area, and the backup node corresponding to the node power supply area can be determined based on the user distribution in the future migration area (that is, the transit node. These two names are only related to the areas to which they belong, and are essentially the same meaning). That is, the future migration area is regarded as the node power supply area, and its center of gravity is used as the transit node, i.e., the backup node, of the corresponding node power supply area, and the optimal backup laying path between the main path and the backup node is obtained as the auxiliary path of the distribution line corresponding to the future migration area.

[0072] The auxiliary path simulation laying module 50 is also electrically connected to the wire type determination module 40, so the wire type determination module 40 can receive the auxiliary path of the distribution line corresponding to the future migration area transmitted by the auxiliary path simulation laying module 50, and then the wire type determination module 40 can also analyze and process according to the preset additional power load data, and select the type of laying wire corresponding to the auxiliary path accordingly to ensure that the load carrying capacity of the selected laying wire type is greater than or equal to the preset additional power load data, so that during the normal use of the laying wire, the normal power demand of each user in the future migration area within the target safe working period is further guaranteed. Exemplarily, the preset additional power load data can be understood as the maximum power load of the future migration area. Exemplarily, the future migration direction and future migration area of ​​the user cluster can be determined by referring to the construction and development plan of the area to be planned, that is, the regional planning book, that is, the estimation of the power load of the corresponding future migration area can be achieved according to the construction and development plan, that is, the preset additional power load data, and the load carrying capacity of the above-mentioned auxiliary path should meet the requirements of the preset additional power load data, that is, the load carrying capacity of the above-mentioned auxiliary path is greater than the requirements of the preset additional power load data, so as to ensure the normal power demand of each user in the future migration area. In this way, the setting of the auxiliary path simulation laying module 50 introduces the consideration of the migration and change of user clusters in the planned area, and the consideration of the future development in the planned area, which is more comprehensive, and further ensures the normal power consumption of users in the planned area and the future migration area within the target safe working period.

[0073] Optionally, continue to refer to Figure 3 The line planning simulation system also includes a wire carrying capacity determination module 60; the wire carrying capacity determination module 60 is electrically connected to the wire type determination module 40, and the wire carrying capacity determination module 60 is used to determine the sum of the wire carrying capacities in the to-be-planned area and the future migration area according to the carrying capacity of the type of laid wire corresponding to the main path, the allocation weight of the type of laid wire corresponding to the main path, the carrying capacity of the type of laid wire corresponding to the auxiliary path, and the allocation weight of the type of laid wire corresponding to the auxiliary path.

[0074] Specifically, the wire carrying capacity determination module 60 is electrically connected to the wire type determination module 40, and the wire type determination module 40 can transmit the type of laid wires corresponding to the main path and the type of laid wires corresponding to the auxiliary path to the wire carrying capacity determination module 60. The wire carrying capacity determination module 60 can determine the sum of the wire carrying capacities in the to-be-planned area and the future migration area according to the carrying capacity of the type of laid wires corresponding to the main path, the allocation weight of the type of laid wires corresponding to the main path, the carrying capacity of the type of laid wires corresponding to the auxiliary path, and the allocation weight of the type of laid wires corresponding to the auxiliary path. It should be noted that the present embodiment determines the predicted power load required for laying wires corresponding to the auxiliary path as one of the feasible solutions. The average value of the power load of the current users is used as a single-household load reference. Combined with the planning of the regional planning book, the number of households of the migrated users is determined. The product of the number of households and the single-household load reference is the predicted value of the predicted power load required for the standby node, that is, the preset additional power load data. The preset additional power load data is used as the maximum power load required to be carried by the laying wires corresponding to the auxiliary path, and the type of wire that meets the maximum power load is selected. In this process, a type of wire that can just carry the maximum power load (that is, the preset additional power load data) can be selected, further avoiding the waste of resources. Exemplarily, the wire carrying capacity is measured in kilowatts or megawatts.

[0075] Further, the wire carrying capacity determination module 60 can determine the sum C of the wire carrying capacity in the area to be planned and the future migration area according to the calculation formula C=W1×L1+W2×L2; wherein L1 represents the carrying capacity of the type of laying wire corresponding to the main path, W1 represents the allocation weight of the type of laying wire corresponding to the main path, L2 represents the carrying capacity of the type of laying wire corresponding to the auxiliary path, and W2 represents the allocation weight of the type of laying wire corresponding to the auxiliary path. In this way, after calculating the predicted power load required for laying wires corresponding to the best backup laying path (that is, the auxiliary path), and the minimum future bearing wire (the wire that can just carry the maximum power load (that is, the preset additional power load data)) that can be provided for the predicted power load, the type of laying wire is weighted again to obtain the final type of laying wire used in the main path. In this way, a more comprehensive development consideration of the area to be planned can be achieved, and normal power supply to the area to be planned can be achieved within the target safe working period.

Exemplarily, the data acquisition module 10 can obtain the user distribution in the area to be planned, the historical power load data of each user, the population growth rate and the economic growth rate in the area to be planned in units of years or months. Exemplarily, a two-dimensional coordinate system or a three-dimensional coordinate system can be established in the area to be planned, and the distribution of each user in the area to be planned can be determined in the form of coordinates, so as to determine the specific laying of the distribution line path according to the distribution of each user in the area to be planned. Exemplarily, the historical power load data of each user in the area to be planned can be obtained by means of electric energy meter records, visits and inquiries. In addition, it should be noted that the sum of the historical power load data corresponding to each user in the area to be planned is the historical power load data of the entire area to be planned. For example, the population growth rate and economic growth rate of the area to be planned can be obtained based on the record information of the relevant departments, so as to determine the predicted future power load data of the area to be planned based on the overall historical power load data, population growth rate and economic growth rate of the area to be planned.

It can be understood that the predicted power load data can ensure the normal power demand of each user in the area to be planned within the target safe working period.

[0083] It should be noted that S120 is a step for determining the main path of the distribution line corresponding to the area to be planned, and S130 is a step for determining the predicted power load data of the area to be planned within the target safe working period. In this embodiment, the sequence of S120 and S130 is only for example and not for limitation. By way of example, S120 may be executed first and then S130, or S130 may be executed first and then S120, or S120 and S130 may be executed simultaneously.

[0084] S140. Determine the type of wires to be laid corresponding to the main path based at least on the predicted power load data.

[0085] Specifically, continue to refer to Figure 1 , the wire type determination module 40 is electrically connected to the power load prediction module 20 and the main path simulation laying module 30 respectively, then the wire type determination module 40 can receive the predicted power load data of the area to be planned within the target safe working period transmitted by the power load prediction module 20, and the main path of the distribution line corresponding to the area to be planned transmitted by the main path simulation laying module 30, and then the wire type determination module 40 can analyze and process the predicted power load data, and select the type of laying wire corresponding to the main path accordingly, so as to ensure that the load carrying capacity of the selected laying wire type is greater than or equal to the predicted power load data, so that in the normal use of the laying wire, the normal power demand of each user in the area to be planned within the target safe working period is further guaranteed. In this way, after determining the main path of the distribution line corresponding to the simulated laying and the type of laying wire corresponding to the main path, the subsequent actual construction process can be carried out. This embodiment effectively improves the construction efficiency and ensures the power demand of the area to be planned.
